I did em when the valley pan was still off so I just looked at the cam and adjusted them when on lowest spot. Took the slack out and went 1/2 turn. Then I would turn motor over by hand and do the next one, right down the line. I don't see how I could've messed that up, but I'm pretty sure I did. Oh well, next weekend maybe it'll run!!!! Glad I didn't seal those valve covers yet. Wanted to get it running and then seal em. I'll look on here for another method. This time with the valley pan on and looking at the rockers. Suggestions, or does it sound like I am on the right track?   |
How do you know that you have no compression? Did you do a compression test, or are you just going by what it sounds like when cranking?
